Camshaft chain lengthening, MVB 93 ?

[ruedisrs6]

Dear gentleman,
I was wondering if someone has recently done a replacement of the cam chain tensioners and chains and might be willing to share (or check) the MVB 93 values of the intake and exhaust cam adjustment values as a reference ? Mine are at -5.0°CV and 0.0°CV (bank 2: -4.0°CV and 1.0°CV) and I just want to know if I can start a crowdfunding campaign for replacement in the near future . Car has 180.000 km.
Many thanks,
Ruedi

It would be very helpful, if someone could share the MVB 93 values of both banks together with the milage. Would at least allow me to see, whether my car is largely deviating from others or not. Many thanks.

No one our there who is able to share the MVB93 data and the milage ? Many, many thanks.

Hope this is of some use, Car is 2010 and has done 66,000 miles

This is definitely of use ! Many thanks for it. Seems that your bank 2 is perfect ! And seems that I need to prepare myself for a chain change.

My car is at 147k km, values are:
Bank 1 intake -4.0
Bank 1 exhaust 0.0
Bank 2 intake -1.0
Bank 2 exhaust -2.0

Are there any specs for acceptable ranges for these values?

What I found during my internet search is that the most conclusive sign of a "pathological" chain stretch is a rattle noise for a few seconds at cold start. From the MVB 93 values there seem to be differences between different engines, but the specs I found are that the limit is +/- 8° KW for throwing a camshaft sensor error which causes then a CEL on. And it seems that the intake cam is the one which reach this limit first. I wrote my initial post to gain more insights and get more information on this.
Maybe there is a gentleman (or woman) out there whose engine had a chain and chain tensioner replacement and might have recorded the MVB93 values before the repair was done.
