Hi I have a e46 and sometimes not all the time when I start it up I get this horrible click click sound about 4 clicks then it runs just fine..? Sounds like tapets but after a second the noise goes and the car runs like a dream...is it something to worry about it?

It will be the tappets... Oil has drained to the sump (natural gravity) and oil in the top of the cam followers (tappets if you like) has done the same. They need replacing but if you can live with it, it won't hurt !!

Yeah it is literally a few seconds then it stops and runs just fine...bit worried it was something to do with timing (a mechanic said) but I didnt trust his diagnosis...if its not going to damage the car il probs just leave it for now ;-) thanks for the advice mate

The "tick" disappears when oil-pressure is obtained, not a bad thing... just annoying sometimes !

Oh, and find a new mechanic ! :lol:

      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
