Hi Amo: Did you manage to obtain a replacement ESS ? My 98 S40 Auto has a similar problem with speed becoming erratic when cruising. I have looked on Ebay but no where can I source an ESS. Its odd that my 98 S40 Auto is reliant on this part for its smooth running. If you found the part 1275139 please can you give me the supplier.Hi,
I am looking to replace my crankshaft sensor on my volvo v40 1998 model. The part number 1275139, but Volvo does not supply this part anymore. Is there any replacement or aftermarket sensor on the market?
