Hi all

 

Long time no post.

 

We have a late 2015/65 Mk3 Superb 150 TDI 4x4. Now on circa 50k miles.

Late last year the engine suddenly got noticeably noisier than usual - a very "tappety" / "ticky" sound, very obvious - you can hear it as the car drives down the road.

It varies directly with engine speed; it's there from cold but does seem to get a little louder when the engine is warm. 

 

Car is driving fine - no change in performance or economy.

No oil loss, mayonnaise, coolant loss. Just the noise.

 

It's in the garage at the moment for some diagnosis, after a listen with a stethoscope they say the noise is roughly from the alternator / fuel pump area.

 

I wondered if anyone else had this issue, and if so, what was the outcome ?

 

Many thanks!

When was the last oil change?

Just following this up, as the cause was discovered yesterday.

 

The cambelt had jumped - apparently the cam was 1 tooth out from the crank, and the HPFP 3 teeth out (so I'm told).

A quick trial with the cam back in time and it was much quieter.

Garage are now fitting new cambelt/tensioner/water pump etc.

 

FSH with Skoda from new (but now at an independent specialist). Cambelt was done previously by Skoda, maybe 3-4 years ago now.

@muddybootsLucky save there.

Are you having the independent doing the servicing on your Haldex?

Did a main dealer do that last time?

 

Main dealer did Haldex previously, good for a while yet.

Further update.

Previously we'd had an issue with a leaking adblue injector, which resulted in a large white buildup of crystallised adblue in the area. The injector was replaced, and all the visible residue removed - but it seems there was quite an unseen buildup inside the adjacent cambelt cover. I'm suspecting a chunk of this fell off at some point and caused the belt to jump.

 

All cleaned now, new cambelt/water pump, fully serviced - and it's all back to how it should be
