BMW EGR valve and EGR cooler problems

Which cars and engines are affected?

BMW and MINI diesels fitted with exhaust gas recirculation (EGR). The EGR cooler is cooled by engine coolant, and on some four- and six-cylinder diesels coolant can leak from it. BMW has recalled a range of these cars.

The models recalled include:

• 1 Series built from November 2011 to September 2017
• 3 Series built from December 2011 to November 2017
• 5 Series built from March 2011 to December 2017
• X3 built from August 2010 to October 2017
• X5 built from April 2013 to June 2017
• MINI diesels built from 2013 to 2017
• 2 Series Active Tourer and Gran Tourer built from 2014 to 2018

Other models are covered too, and the recall notices do not list engine codes, so the only reliable check is by registration on gov.uk. Do this before you book EGR work with us. For other work on these cars, see our BMW and MINI specialist page.

What are the symptoms?

BMW’s recall notices do not list warning signs for the driver. A car can be inside the recall and still feel normal, so do not wait for a symptom before checking.

If your car is outside the recall and you have a warning light or a concern about the EGR system, tell us when you book which lights are on and how often, if at all, you have had to top up the coolant.

What causes it?

On the recalled cars, coolant leaking from the EGR cooler can form deposits that, in rare cases, can catch fire. BMW’s remedy is a revised cooler and an engine software update.

On cars outside the recall, the EGR valve or the cooler can still be at fault. We find out which by testing, not by guessing.

How do you confirm the fault before fitting parts?

A fault code is not a repair. Before we quote for any parts, we:

• check your registration for an open recall, and send you to BMW’s network if there is one
• read the fault memory with our diagnostic equipment
• inspect the EGR valve, cooler and pipework
• test the part we suspect to prove the cause

Under the recall, BMW’s own check is an internal inspection of the cooler. Outside the recall, we show you what we found, with photos, and send a written price. No part is fitted until you give your written approval.

What does the repair involve?

Under the recall, BMW fits a revised EGR cooler and updates the engine control software, free at a BMW retailer.

Outside the recall, we replace the part the tests prove faulty, whether that is the EGR valve or the EGR cooler, using the correct part for your engine. Once the work is done, we check that the fault has cleared and verify the repair, including a road test where appropriate. We repair EGR systems and keep them working; we never remove or disable them.

Can the EGR valve be removed or blanked off?

Not by us. In the MOT, emission control equipment that is missing, obviously modified or obviously defective is a Major defect, and EGR valves are among the parts named.

The Department for Transport consulted in 2026 on tighter rules against emissions tampering, naming EGR manipulation alongside DPF removal.

How long does an EGR repair take?

It depends on what the tests find, and on whether the valve or the cooler is at fault.

Before any work starts, you get a written price and a promised time for your next update. If the car needs to stay with us, ask about a courtesy car when you book.

Is there a recall for the EGR cooler?

Yes, several. The DVSA recall listings include R/2018/258, R/2018/341, R/2020/179, R/2021/037, R/2022/206, R/2022/255, R/2022/256, R/2023/172 and R/2023/174, across BMW and MINI diesels.

Whether a recall applies depends on the individual car, so check your registration on gov.uk. Recall work is done by BMW’s network, not by us.
