Got a new coil in the mail a few months ago for my MK3 Gti. I ordered it because the old one had a too high primary resistance (1.2 ohms). According to the manual it should be between 0.72 and 0.88 ohms for DOHC's and between 1.13 and 1,38 ohms for SOHC's.
This new coil has 1.2 ohms as well, even though it's for the DOHC-model according to Rockauto(never got a wrong part from them). So do you guys think both my coils are for SOHC-models, or was the GTi-coil different on MK3's? The manual I have is the "89 GTi shop-manual".... was there ever another manual released after that one?

PS: The car runs without issues in my opinion, but this is the only Gti I've ever driven; so I couldn't tell if there was an impact on performance if I was indeed using the wrong coil.

This is what I currently have: BECK/ARNLEY Part # 1788172

If someone has info about this, please share... don't want to spend more money on this without knowing what the correct part is.

Maybe your ohm meter needs calibration; and for the record yes the coil for a GT is different.

i am sure its E-coil... so same for both mk2/3 gti... for coil cylinder is for g10t only... g10 has mini E-coil... not sure about sohc version..

1.2 is not too high for primary coil... i will try to re-check the gti service manual... will post if i found ;]

Here's a picture of the 89 Gti Shop-manual...

I doubt the manual is wrong, as all my other manuals say the same; but maybe something changed with the Mk3. I'm surprised no one ever noticed this though...

No updates on the resistance?

My Question is that we can use a coil from any car once it is within resistance range according to the workshop manual

I still haven't found anyone who can measure the resistance of an "original" Gti coil. I'm still running mine as it is. but it's definitely not within specs according to the 89 Shop-manual.

Interesting...is your car an mk3 as well? Maybe different coils were used on these models, or the aftermarket coils are ALL out of spec :?...

Can you guys tell me what is the primary and secondary for me to check? Is there any difference on upgrading to an aftermarket coil like msd ss?
