BMW B47 / N47 EGR Cooler Fire-Risk Recall NSC R/2018/151
DVSA recall NSC R/2018/151 is the most important verification step on any UK BMW diesel purchase with the N47 or B47 engine. The recall covers ~320,000 UK BMWs (320d, 520d, X1 20d, X3 20d and many more). The remedy is free at any BMW dealer. This guide covers what the recall is, how to verify completion, what to do if it's outstanding, and how to negotiate around it.
Quick answer
Every UK BMW N47 or B47 diesel (320d, 520d, X1, X3, X5 25d) is covered by this recall. The remedy is free at any BMW dealer. Verify completion on the VIN at gov.uk/check-vehicle-recall before buying. If outstanding: book a free BMW dealer appointment and treat it as a half-day collection trip. Don't let a seller charge you for it; it's free.
What causes the problem?
The EGR (Exhaust Gas Recirculation) cooler is a heat exchanger in the N47 / B47 diesel intake system that uses engine coolant to cool exhaust gas before it re-enters the intake manifold. BMW identified a manufacturing tolerance issue where the cooler's internal walls could fail, causing coolant to leak into the intake. In rare cases, coolant entering the manifold could ignite, causing an engine-bay fire. DVSA opened recall NSC R/2018/151 in 2018 covering the affected production. BMW's remedy involves replacing the EGR cooler with a redesigned unit and verifying the coolant system is clean. Free at any BMW dealer, takes around 3-4 hours.
Symptoms, what to listen and look for
- Coolant level dropping with no visible external leak (the coolant goes into the combustion chamber via the EGR system).
- White smoke from the exhaust at startup or under load (coolant being burned).
- Sweet coolant smell from the exhaust after motorway driving.
- DVSA / BMW recall letter sent to the V5 registered address (may be at a previous owner's address if VIN hasn't been transferred to current keeper).
- Outstanding 'open campaign' status when checking VIN at a BMW dealer.

What evidence should a buyer ask for?
- Open the gov.uk/check-vehicle-recall page and enter the VIN; should report 'No outstanding recalls' or list NSC R/2018/151 as completed.
- Ask the seller for the BMW dealer letter confirming the recall has been completed (older sellers may have this in the service folder).
- Check the digital service record (DSR) at a BMW dealer for the campaign work entry; any BMW dealer can pull this with the VIN.
- Inspect the EGR cooler / cover under the bonnet for evidence of recent service (clean fasteners, fresh seal).
- Verify no current coolant warning lights or coolant top-ups in recent service entries.
Buy, negotiate, or walk away
Buy
Recall verified completed; documented in service history; gov.uk shows no outstanding recalls.
Negotiate
Recall outstanding (book a free BMW dealer appointment; treat it as half a day's collection trip; don't let seller charge for it).
Walk away
Active coolant warnings, white smoke at startup, or seller refuses to book the free recall remedy. Active damage from coolant ingress can be £500+ even after the free EGR replacement.
Long-term ownership verdict
Once the EGR cooler recall is completed, this concern is gone for the life of the engine. The replacement uses a redesigned unit and the failure pattern doesn't recur. The N47 / B47 fleet has now been progressively addressed over the 7+ years since the recall opened; most cars in the UK used market have already had the remedy done. For any unverified car, treat the half-day BMW dealer trip as part of the purchase ritual; for verified cars, this is no longer a buying concern.

Frequently asked questions
What's the BMW EGR cooler recall NSC R/2018/151?
DVSA recall covering ~320,000 UK BMWs with N47 and B47 diesel engines. The EGR cooler could fail and allow coolant into the intake manifold; in rare cases this caused engine-bay fires. BMW's remedy replaces the EGR cooler with a redesigned unit free at any BMW dealer.
Is the BMW EGR recall free?
Yes. The recall remedy is free at any BMW dealer regardless of car age, mileage, or service history. The DVSA mandates free remedy for safety recalls. Don't pay any seller or third party for this; book directly with BMW.
How do I check if my BMW has the recall outstanding?
Go to gov.uk/check-vehicle-recall and enter the 17-character VIN. The page will report any outstanding recalls and any completed work. You can also ask any BMW dealer to check the VIN against open campaigns; this is free.
Which BMW models are affected?
Every UK BMW with the N47 (2007-2014) or B47 (2014-present) diesel engine. This includes 320d, 520d, 118d, 318d, X1 20d, X3 20d, X5 25d, and many more. If the V5 says 'Diesel' and the badge is xxxd on a post-2007 BMW, the recall almost certainly applies.
How long does the recall remedy take?
Around 3-4 hours of workshop time. Most BMW dealers can complete it as a day's appointment. Book in advance; recall work is scheduled around regular service load.
What if the recall has already been done?
You're fine. The replacement uses a redesigned EGR cooler that doesn't share the failure pattern. The concern is gone for the engine's life. Verify completion via gov.uk/check-vehicle-recall and move on.
Can I negotiate the recall as if it were a service item?
No, but it can be used as a 'this car has been neglected' signal. The recall is free; you can't legitimately deduct money for completing free work. However, an outstanding recall years after notification suggests the car hasn't been routinely serviced at BMW or properly maintained, which is a legitimate broader negotiation point on service history and overall care.
What if the car has had coolant ingress damage before the recall was done?
Verify on test drive: white smoke at startup, sweet exhaust smell, coolant top-up history. If there's evidence of past ingress (not just the recall risk), factor in £200-£600 for cleanup of intake / MAF / glow plug damage in addition to the free recall remedy.
Is the F40 1 Series affected?
Yes. Any F40 with B47 diesel engine (116d, 118d, 120d xDrive) is covered. Verify on the VIN at gov.uk/check-vehicle-recall.
Will my BMW be unsafe to drive if the recall is outstanding?
BMW classifies the risk as 'low frequency, high consequence' (fires are rare but serious). Driving the car is not prohibited; BMW recommends booking the recall promptly. If you see white smoke at startup or coolant warnings, stop driving immediately and contact a BMW dealer.
