How to tell the difference between a 110 and 90 tdi?

[Beefy-Toledo]

As above i just want to know how to identify each visually in a 2001 toledo. The car had an engine change before i bought the car and just want to confirm its still a 110. cheers guys. chris

check the engine code on it if there is one visible

most obvious is a bar code label on the timing cover which is changeable but iirc there is a stamped code also somewhere

a black cloud smoking diesel buff will be along in a sec

The engine number is stamped into the edge of the block along the bellhousing joint. Difficult to see and take pictures of. Best I can do is below.

Detail showing part of engine number, brightened up.

Barcode label on the timing belt cover is less reliable, may not have been changed with engine.

You'll have to take the engine cover off to read it as well.

TDI 110 codes are likely to be ASV or AHF; AVG and AFN are also 110's
TDI 90's may be ALH or AGR; AHU or ALE is also possible

Thank you for your help mate. that info was very useful and helped me identify that it is a 110 asv

By the way im guessing the turbo spooling being very audible is normal with a straight through exhaust system? deffo not a boost leak or anything as the turbo pulls very well.

Thanks again for that info.

obviously we dont know what you mean by 'very audiable' but yes a straight through does help this a little.
