GRAP Stage 3 & 4: Is Your BMW, Mercedes or Audi Diesel Allowed in Delhi NCR?
October 2026. Rules change quickly in winter, so always check the latest CAQM and Delhi Transport Department orders before driving.
Every winter, the same question lands on our WhatsApp at Wheel Force Centre: “GRAP 3 is coming. Can I still take out my 2017 BMW 520d?” The honest answer depends on two things: your car’s Bharat Stage (BS) emission norm and where it’s registered. It does not depend on the badge on the bonnet.
This guide explains the current rules for 2026 in plain language, so owners of luxury cars in Delhi, Gurugram, Noida, Ghaziabad, Faridabad and Sonipat know where they stand.
WHAT IS GRAP, QUICKLY?
The Graded Response Action Plan (GRAP) is the emergency anti-pollution plan for the National Capital Region. It’s run by the Commission for Air Quality Management (CAQM). It has four stages that switch on as Delhi’s AQI rises:
– Stage I – Poor: AQI 201-300
– Stage II – Very Poor: AQI 301-400
– Stage III – Severe: AQI 401-450
– Stage IV – Severe+: AQI above 450
CAQM revised the GRAP schedule on 29 September 2026. For private car owners, the biggest change is that the Stage III car restriction now also covers Sonipat, alongside Delhi, Gurugram, Faridabad, Ghaziabad and Gautam Buddh Nagar (Noida).
WHAT EACH GRAP STAGE MEANS FOR PRIVATE CARS
Stage I and Stage II
These stages don’t restrict private cars based on BS norm. They focus on dust, construction, diesel generators, buses and enforcing PUC certificates. Expect stricter PUC checks and higher parking charges, but your car can still be driven.
Stage III: the one that hits older diesels
Under Stage III, authorities impose “strict restrictions on plying of BS-III petrol and BS-IV diesel or below-standard four-wheelers” in Delhi and the five high-traffic NCR districts listed above.
That means:
– BS-IV diesel (most luxury diesels sold before April 2020, like the BMW 520d/320d/X1/X3/X5, Mercedes E250d/C220d/GLE, and Audi A4/A6/Q5/Q7 TDI) is restricted.
– BS-III (or older) petrol is restricted.
– BS-IV petrol is not covered by this restriction.
– BS-VI petrol and diesel, CNG and EVs are not covered.
– There’s an exemption for BS-III petrol and BS-IV diesel cars specially adapted for persons with disabilities and used only for their personal use.
Stage IV
Stage IV keeps all the Stage III car restrictions and adds heavier measures, mostly on trucks, goods vehicles and construction. For example, only CNG, LNG, electric and BS-VI diesel trucks may enter Delhi. The revised schedule doesn’t add a separate blanket ban on BS-VI or BS-IV petrol private cars, but state governments can add measures like work-from-home or odd-even. Check the day’s official order.
Separate from GRAP: Delhi’s Winter Action Plan entry rule (1 Nov 2026 – 31 Jan 2027)
On 20 October 2026, the Delhi government announced that petrol and diesel vehicles registered outside Delhi that are below BS-VI will not be allowed to enter Delhi from 1 November 2026 to 31 January 2027, whatever the GRAP stage. CNG, electric, emergency and essential-service vehicles are exempt, and Delhi-registered cars are not covered by this rule. Details of how it will be enforced at the border hadn’t been announced at the time of writing.
So a Gurugram-registered BS-IV petrol Mercedes is fine under GRAP Stage III in Gurugram, but it may not be able to enter Delhi during the Winter Action Plan period.
QUICK TABLE: IS YOUR CAR ALLOWED?
(Please build this as a table on the page. Columns: Car type | Stage I-II | Stage III | Stage IV | Delhi entry, 1 Nov-31 Jan, non-Delhi registration)
– BS-III petrol or older: Allowed* | Restricted | Restricted | Not allowed
– BS-III diesel or older: Allowed* (but see the 10/15-year rule) | Restricted | Restricted | Not allowed
– BS-IV petrol: Allowed | Allowed | Allowed** | Not allowed
– BS-IV diesel (e.g. pre-2020 520d, E250d): Allowed | Restricted | Restricted | Not allowed
– BS-VI petrol / diesel: Allowed | Allowed | Allowed** | Allowed
– CNG / EV: Allowed | Allowed | Allowed** | Allowed (exempt)
*Pre-BS-IV cars past 10 years (diesel) or 15 years (petrol) can face end-of-life action. See below.
**Unless the government adds an extra Stage IV measure (such as odd-even) on that day. A valid PUC is always needed.
FINES: WHAT YOU COULD PAY
– Driving a restricted car during GRAP: news reports put the fine at up to Rs 20,000, and repeat offenders can have their car impounded. Traffic police have mostly booked these under the Motor Vehicles Act. Check the exact section and amount on your challan.
– Driving without a valid PUC: up to Rs 10,000 under the amended Motor Vehicles Act. Repeat violations can lead to impoundment.
– “No PUC, No Fuel”: under the Winter Action Plan, Delhi fuel stations won’t sell petrol, diesel, CNG or LPG to vehicles without a valid PUC. Cameras that read number plates (ANPR) are being used at about 500 pumps.
THE 10/15-YEAR RULE: WHERE IT STANDS NOW
On 17 December 2025, the Supreme Court changed its earlier order. Authorities may not take coercive action against BS-IV and newer vehicles only because a diesel is over 10 years old or a petrol over 15 years old. Vehicles below BS-IV (BS-III and older) that are past those ages are not protected and can be acted against. The case is still being heard, so this could change.
In practice: a BS-IV 2014 Audi Q7 diesel isn’t scrapped just for its age, but it is still restricted under GRAP Stage III/IV. A BS-III 2009 diesel is at real risk of being seized.
WHY PUC CENTRES SOMETIMES REFUSE OLDER DIESELS
Owners tell us PUC centres sometimes turn away older diesels, or the car simply fails the smoke (opacity) test. The usual reasons on luxury diesels are:
– A choked DPF (diesel particulate filter): short city drives in traffic stop the filter from cleaning itself.
– A stuck or sooted EGR valve: this raises smoke and sets off warning lights.
– Worn or leaking injectors: fuel doesn’t burn properly, so you get black smoke.
– AdBlue/SCR faults on newer BS-VI diesels: low-quality AdBlue or faulty NOx sensors.
– Dirty air filters, boost leaks or warning lights: some centres won’t test a car with an active engine warning light.
We can’t tell you whether a particular centre’s refusal was correct. But a healthy, properly maintained engine is the best way to pass the test the first time.
HOW TO FIND YOUR CAR’S BS NORM
1. RC (registration certificate): check the “Emission Norms” field.
2. VAHAN / Parivahan: go to the vehicle-related services on parivahan.gov.in, or the “Know Your Vehicle Details” option, and enter your registration number.
3. mParivahan app: add your vehicle to see its fuel type, registration date and, usually, its emission norm.
4. Rule of thumb: BS-VI became mandatory nationwide from 1 April 2020. Cars sold before that are mostly BS-IV, but some were BS-VI early, so check your car rather than guessing.
PRACTICAL TIPS FOR LUXURY DIESEL OWNERS THIS WINTER
1. Keep your PUC valid, always
Set a reminder about 2 weeks before it expires. Without it you can’t get fuel in Delhi this winter.
2. Get a pre-winter emission health check
Before you go for the PUC, get the DPF, EGR, injectors, sensors and air intake checked, and clear any fault codes properly. That way you don’t fail the smoke test in the middle of winter. Read our guide on how to keep your car non-polluting this winter and the common winter car problems.
3. Plan for Stage IV days
– Use your household’s petrol (BS-IV or later), BS-VI, CNG or EV car if you have one.
– Take the Metro, use cabs or carpool for office trips. Many offices go hybrid during Stage IV.
– Use the restricted days to book your diesel’s service or repairs, so it’s ready when the restrictions lift. With pickup and drop, you don’t need to drive it yourself.
4. Think long-term
If you have an older BS-III diesel, or keep losing days to GRAP every winter, it may be worth talking through the options with your family and insurer: selling, upgrading or a registered scrappage centre. Servicing outside the dealer can cut running costs too. Here’s how to service outside the dealer without losing warranty.
FAQ
1. Can I drive my BS-IV BMW 520d in Delhi during GRAP Stage 3?
No. BS-IV diesel four-wheelers are restricted in Delhi and the NCR high-traffic districts under Stage III and Stage IV, except for specially adapted cars for persons with disabilities.
2. Is my BS-IV petrol Mercedes allowed under GRAP 4?
Under the current CAQM schedule, BS-IV petrol cars aren’t covered by the Stage III/IV car restriction. But if your car is registered outside Delhi, the separate 1 Nov-31 Jan entry rule doesn’t allow non-BS-VI cars into Delhi.
3. Does the restriction apply in Gurugram and Noida too?
The Stage III/IV car restriction applies in Delhi plus Gurugram, Faridabad, Ghaziabad, Gautam Buddh Nagar (Noida) and, since September 2026, Sonipat.
4. My diesel is more than 10 years old but BS-IV. Will it be seized?
Under the Supreme Court’s 17 Dec 2025 order, BS-IV and newer cars shouldn’t face coercive action only because of their age. GRAP and PUC rules still apply. The case is ongoing, so keep an eye on updates.
5. What is the fine for not having a PUC?
Up to Rs 10,000 under the Motor Vehicles Act, and you also won’t get fuel in Delhi under “No PUC, No Fuel”.
6. How do I check if my car is BS-IV or BS-VI?
Check the emission norm on your RC, or look up your registration number on VAHAN/Parivahan or the mParivahan app.
