Title: Do I need a new knock sensor?
Post by: motah33 on 31 May 2014, 23:51: I've got a GTI 8v 1.8 1990/H Engine code PB.

The housing of the knock sensor got cracked and I don't know if I need a new one or if I can put some sort of sealant around the sensor.

On this thread [http://www.golfgtiforum.co.uk/index.php?topic=132875.msg1191405#msg1191405] the part number was given as
054905377G. When searching for this, the closest match on the list of compatible vehicles was this one: 1990-1992 Volkswagen Golf GTI 16v. Does the 16v GTI use the same sensor as the 8v GTI?

Thanks

0261231013 - Bosch number
053905377 - VW number

Is this a good replacement as I see it's more available:

054905377G

Thanks

Post by: Santiago on 01 June 2014, 20:11: 054905377G appears to be what is currently suggested by VW for a 1990 PB:

Post by: motah33 on 05 June 2014, 04:02: This is where it can get confusing:

1. There is a 054905377 (non-'A') version which is for Mk2 Golf G60 and Mk2 Jetta G60 (http://www.vwheritage.com/vw_spares_Knock-Sensor-Golf-Jetta-Mk2-PG-engines-G60-054905377_act_shop.product_pID_33486712.htm?crumbStartPage=2&crumbStartRow=30)

2. There is a 054905377A which is for Mk2 Golf and Mk2 Jetta (http://www.vwheritage.com/vw_spares_Knock-Sensor-Mk2-Golf-GTI-8v-16v-740mm-green-check-size-054905377A_act_shop.product_pID_33487453.htm?crumbStartPage=2&crumbStartRow=30)

3. Then there is the one from the parts catalogue that Santiago posted - 054905377G (http://www.partscats.info/volkswagen/en/?i=cat_vag_models&brand=vw&number=1658&set=1675&ein=1990&f=110&hauptgr=1234567890&hg=9&grf=020900014&bf=209&hgug=906&ug=06&parent_id=514097&detail_id=514099)

I'll see if I can check with my local VW garage and see what they say.

Post by: h8v on 05 June 2014, 10:34: The difference in those two VW Heritage ones seems to be in the cable length. A phone call to VWH would clarify the issue.

The final letter in the part numbers is often just to indicate that the previous part has been superseded; tiny modifications which have no practical relevance are always taking place.

My guess is that if the connector plug is the same colour as your original, and the cable length is the same, then it will be suitable.

Post by: motah33 on 05 June 2014, 12:56: This is the reply from my local VW:

"The difference between the Part Numbers that you have given me is that 054905377A is a 740mm Knock Sensor with harness, suitable for PL, PF and RV engines between 1986 and 1989 (or 1993 for Golf Cabriolet), whereas 054905377G is a 535mm Knock Sensor with wiring harness suitable for PG, PB, PF, PL and RV Engines between 1990 and 1998 (or 2002 for Golf Cabriolet)."

So, for my PB engine, I need the 054905377G one.

Post by: motah33 on 08 June 2014, 02:31: Some interesting info for those looking for the original Bosch one: 0261231013. This guy is selling them: http://www.ebay.co.uk/itm/261487975413?_trksid=p2055120.m1438.l2649&ssPageName=STRK%3AMEBIDX%3AIT

It works about £24 including delivery from the U.S.

Post by: Santiago on 08 June 2014, 09:19: Will be a few pounds more by the time you get to the checkout. The line that starts "Import charges $0.00" is deceptive, where it says "(amount confirmed at checkout)" you'll find that it is confirmed at rather more than $0.00.
Title: Re: Do I need a new knock sensor?
Post by: motah33 on 08 June 2014, 14:45: There shouldn't be any import charges. The value is too low for import duty for the UK anyway. I've used the system before for much higher value items and the charges they say are the charges I paid - nothing more:

"This amount includes applicable customs duties, taxes, brokerage and other fees. This amount is subject to change until you make payment. If you reside in an EU member state besides UK, import VAT on this purchase is not recoverable. For additional information, see the Global Postage Programme terms and conditions"
