&........................... Just responed with this:-
"Strange one then, as all 150 engines have a frount mounted intercooler. Have you got the engine code, at all? (It has 3 letters & can be found in the handbook, on a sticker in the spare wheel well, or engraved on the engine itself (under the plastic cover).
ps As you know, all 25th Anniversary Golfs were numbered as they were a limited run. Can you tell me which no. this one is, please.
Thank you."
