Hi all

I've getting a sighing noise from the car as I come off the throttle (I know it's a diesel so doesn't have one!) and I'm a bit puzzled by it. It sounds like a release of pressure so I'm thinking possibly turbo related?

It's done 138k miles, the vast majority on motorways, and is still pulling strong. There's no sign of any smoke and the turbo itself sounds like it always has.

Any thoughts?

Thanks

Steve

Could be a waste-gate release or leak in hose(s)... HTH ;)

      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.

      Z3 airbag wiring,

      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
