BMW 5 Series EGR delete

The BMW 5 Series has always been a popular company car. That means high mileage, short urban runs, cold starts from motorway services and a lot of stop-start driving, precisely the conditions that cause EGR systems to fail fastest. By the time a 5 Series reaches its second or third owner, EGR problems are often already present.

We carry out a software-based ECU remap through the OBD port. No engine strip, no parts removal, we come to you and the job is done in under an hour.

Engines and variants we cover

F10 520d, N47 and B47

The F10 520d is the bread-and-butter of the 5 Series range and the one we get called to most. N47-engined examples from 2010 to 2014 are particularly prone to EGR cooler failure. The B47 (fitted from late 2014 in the F10 LCI and carried through to the G30) is more modern but still develops EGR valve sticking faults in service.

F10/G30 525d and 530d, N57 and B57

The six-cylinder diesel variants are fitted with the N57 or B57 engine. EGR cooler failure on the N57 is a known issue, especially in vehicles that spent their early life doing short, cold runs under a lease agreement. The B57 in the G30 530d is newer but not exempt, we are already seeing EGR valve sensor faults on higher-mileage examples.

F10 535d, N57T

The tri-turbo N57T in the 535d is a capable engine. EGR faults on this unit are less frequent but when they occur they tend to come with multiple fault codes and a confused ECU. The remap resolves it cleanly.

Why EGR systems fail on high-mileage company cars

Company car diesels spend a disproportionate amount of their lives on cold motorway runs, the engine barely reaching operating temperature before the driver arrives at a service station and switches off. Soot and carbon deposits accumulate in the EGR cooler and valve faster than on a vehicle that regularly gets a proper run. The result is cracking coolers, stuck valves and coolant loss.

ECU delete removes EGR function from the engine management system entirely. The valve and cooler are left in situ, they simply stop operating.

Frequently asked questions

Is this for road use?
No. EGR delete is for off-road and track use only and is not compliant with road emissions requirements. You confirm this when you book.
Do you need keys or access to the interior?
We need access to the OBD port, which is inside the cabin. Beyond that, the vehicle does not need to run during the remap, just ignition on.
Will the fault codes come back after the remap?
No. Once the EGR delete is written to the ECU, the engine management system stops monitoring EGR operation. There is nothing left to trigger an EGR fault code.
What if my 5 Series has other fault codes alongside the EGR?
We will tell you what we find. If there are non-EGR faults we will flag them. Clearing unrelated codes is not part of this service unless agreed separately.
Can you remap a company fleet vehicle at our depot?
Yes. If you have multiple vehicles at one location we can work through them on the same visit. Call to arrange.
