Del Boy 76 Posted March 8, 2019 As the title says. I’ve got a BMW 320i with a random misfire issue. Changed all the plugs and coils. The misfire keeps moving around randomly and sometimes not at all! I drove it about 20 miles the other day and it was perfect! Then all of a sudden...random misfire again. No other codes stored apart from the cylinder(s) with the misfire. Has anyone come across this before? Thanks Share this post Link to post Share on other sites
justina3 518 Posted March 8, 2019 I think that is way to random for anyone to pin point, i had a clio do that once and turned out to be a snapped spring on the lifters, why it kept moving we put it down to being french. Share this post Link to post Share on other sites

It doesn’t rattle or make any noise though? Or does that not matter? Vin: WBADV52010E653935 Share this post Link to post Share on other sites
Grantlfc81 88 Posted March 8, 2019 Doesn’t matter, I’ll let you know shortly Yes needs all 3 -Timing chain check(at dealer) will be classed as a Brake retrofit check. Will be a free timing chain install. -Battery cable. (Extremely urgent car can cut out mid driving and lose all power. I’ve hard this twice. -Blower wiring (can catch fire) Can do the wiring Monday.

Grantlfc81 88 Posted March 8, 2019 Hi mate, yes, virtually all of the petrol 4 cylinder engines suffer from timing issues. 25% of the ones we buy need new timing chains. Some get done under warranty. Share this post Link to post Share on other sites

Ive given up with the main dealers, after we had a 60k BMW X1 2.0d go in 1 week out of warranty, for a extremely rattly chain on cold start up that they wanted us to pay them to put new tappets in!

Nick M.K. 574 Posted March 9, 2019 Always use Sytner if you have one anywhere near you. They have a dedicated team that will chase Bmw to authorise warranty work if it’s required and if the car is near the warranty parameters. You might need to pay some contribution but usually a small % Share this post Link to post Share on other sites

Thanks for looking into this Grant - however I have just spoken with my local BMW who tell me the only recall outstanding s for the drivers airbag, not the chain Share this post Link to post Share on other sites
Nick M.K. 574 Posted March 9, 2019 (edited) Have you scanned the car? Have you got a code with no EML: "DeNOX Catalytic converter sulpherised"? Edited March 9, 2019 by Nick M.K. Share this post Link to post Share on other sites
Del Boy 76 Posted March 9, 2019 Yeah its been scanned loads to times - it just says misfire and the cylinder, which keeps changing Share this post Link to post Share on other sites

I had issue with one years ago, I cant remember the ins and out but I had to replace all 4 with genuine BMW items as the aftermarket ones were crap. Might be worth checking if all injectors look the same incase one or two have been changed before. Share this post Link to post Share on other sites

Grantlfc81 88 Posted March 10, 2019 Yes, it won’t stretch again after, just give me chassis and I can get what recalls are required. its the ‘brake retrofit’ which is code name for timing chain you need to look out for. there is 3 or 4 recalls on BMW’s between 2007-2011 batery cable to ecu melting timing chain Air con blower And one more but I’m hungover so can’t think Share this post Link to post Share on other sites
