Mein Auto: 3 Series E46
Timing Chain/Tensioner

Hello!
Wondering if anyone is able to help me at all?

Recently bought my 3 Series E46 Love it! It has a lot of miles (148k miles) on it but has been services regularly.

I've got some rattling and low speeds. No major biggie I hope.
But the other forums I read said it could be the timing chain. Of course I've read that the chain should last the life of the car, but can slack. And a new tensioner should help with this. I seem pretty confident I could do this myself. Or failing that take it to a garage with the part and get them to do it.

But I'm just thinking in advance, if its still an issue, how much would a replacement Timing chain cost in labour?
Any answers from UK price would be appreciated, otherwise I would still appreciate any info and I can work out roughly the UK price.

Many Thanks in advance!

Try recording the sound and posting the file. Also, record the sound via video and post it on YouTube. Post the link.

Here's the link to the video.
It sounds pretty faint but it can be heard. It's like a metallic Rattle. Only slight though

Mein Auto: Bmw 318ci
I had a very similar issue very recently, as well as the sound i had severe loss of power and car would just stall after start up, one day it was fine and the next that happened. Im from london and have an e46 318ci convertible, came up with camshaft sensor codes but turned out that the chain skipped a tooth and chain guide was worn which caused that. Just got car back two days ago after engine had to be retimed and guider replaced, cost for that was 250 labour and had to purchase the timing tools for the n42 which most garages dont have which was 80 but varies. All in all a good price as others qouted 500 +. It seems like your chain is skipping a tooth i believe.

That is good news! Thank you.
Fortunately I only use it at the weekends.
But I'll start having a call round and get quotes
Thanks for your help!
