Hi guys,

Have you got a multi meter? If so charge the battery over night. Start the car up and put your multi meter on + and – and see if you are getting 13v+, any less than that and you have a charging problem.

Does it run and drive 100% once jump started? If so and it is charging the battery it could be a battery drain, test to see if it is charging then come back to me

... Also check that all the cables are tight at the alternator.

      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

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

      Hey everyone, I’m thinking about buying a 2021 BMW X3 and want to make sure I’m covering all my bases before making a decision. I’ve heard about VIN decoders and how they can give you details about a car, but I’m not sure what kind of info they actually provide. Do they show anything useful, like accident history or open recalls? Or are they just for basic specs? If you’ve used one that worked well, I’d love to hear about it and any tips for getting the most out of it. Thanks so much!
