Thumbs down Disappointing LCi 330d problem & Main stealer doing what they do best!

Just thought i'd share and inform of the repair that has just been carried out on my 58plate 330d with the N57 engine. I had a rattley/rotary type noise on idle and between 1500-3000ish rpm. After a few attempts including changing the Aux drive belt on the front the engine, my car has been into my local 'stealers' (no names mentioned but within 10miles of Tamworth, Midlands) for the replacement of the Guide rails and associated parts. Fortunately under warranty as the car is under 3yrs old.

I believe it to be very similar to this thread:-

I was shown the original warranty claim form listing oil and filter change, however after i mentioned that the car was due a service within 1900 miles the oil and filter were miraculously removed from the list i was shown and that to have the oil renewed i needed to pay for it! Now there's a SURPRISE! Obviously i'd offered to pay the parts and labour for the other parts required on the service but they refused to budge. Whatís more is that i have been charged the labour for the Oil and filter part of the service!

The original diagnosis of the guide rails being worn at just 58,000miles, I was told that the guide rails in actual fact distort causing the chain to bounce and rattle... not worn apparently?! Long and short of it but the unnamed stealer (very appropriately named!) informed me that they actually re-use the old engine oil... OUTRAGEOUS! And they can guarantee that there isnít any debris or contaminant from the faulty parts as they are only 'distorted' and not in actual fact worn. Absolute BS!

Whatís more is that i have heard since of X3's with the N57 engines (Highways police and high miles) that have suffered snapped timing chains!!

So N47/N57 engine owners i urge you to check for this noise! The Timing chain guides on the N47/N57 are common parts.
