Take a look at www.newtis.info its a BMW technical information site same as dealers use. You should be able to find what you need on there.

  • Not a BMW but we did clean my sons Toyota, straight forward job. We couldnt believe the amount of soot in the EGR and the inlet tract we had a henry hgover running all the time to suck out any loose stuff while we cleaned. Still when he floored it once on the dual carriage way he said it look like a special effect from a Harry Potter movie behind him as everything was enveloped in a huge black cloud, the up side by the time anyone emerged he was long gone. The black cloud only happened once and performance was back to normal so success

I had an EGR problem with my 325D but cleaning wouldn't have solved it. After nearly 70,000 miles, a leak had developed causing exhaust to penetrate into the actual mechanism which led to it's sticking. Only solution was a new valve which came out at £260 including fitting. This was at an independent garage, not a main agent but the new valve was genuine BMW part. (According to the garage owner, I could have asked for proof but felt it unnecessary).

You say in your post it's your mates car, depends on vintage and mileage.

Hi Donny

That's a fairly low mileage for a 2016 car. This might suggest frequent small journeys rather than long commutes or travelling greater distances.

If so, take the car for a 200 mile drive so it gets good and hot all the way through and this may help in clearing carbon build up.

Otherwise a clean of the valve may be necessary following the instructions posted earlier.

I would suggest he checks with the Franchise to see if his car is part of the recall or not. If so, Robert's your father's brother.

      Low Oil Pressure Light on E90

      ***OIL PRESSURE WARNING SOLVED***BMW E90 with same issue. Intermittent Oil Pressure Warning light for around a year. No performance issues or strange noises.Started when slowing down coming off highway and then progressed to when driving around town as well.Tried a can of Wynn's Super Charge Oil Treatment and after a few days light stopped coming on around town but still after highway driving. Bought another can and poured that in and six months later no warning lights. Guessing will have to do this again after next oil change but so far so good. Car running and sounding better also.

      Hi Jay You will need a Diagnostic Program to turn off an Airbag light if someone has triggered the light that could also be the issue Dave

      Can a VIN decoder really help me check a car’s history?

      Hi David Welcome to the Forum A Vin decoder is a useful tool as it lets you know what was on the original cars build sheet but that only tells you what toys it should have. As its a 2021 car it will have had one MOT which hopefully is clear of any advisories, you can check recall and MOT at www.gov.uk/check-mot-history Next check all tyres are correct and in good condition odd or mismatched tyres can cause havoc with Transfer cases Transmissions and diffs. The rest is History History History plus making sure everything works as it should Good Luck Dave
