VW Golf Mk2 Owners Club

Hey in regards to your dash led upgrade did you have to replace the original circuit board or just modify it?

Interesting, that bit isn’t on my early example. https://www.vwgolfmk2.co.uk/clubforum/index.php?topic=18.0

I need to check my 91.

My car's one of the run out models and registered in January 1992, so I always knew it was from the end of MK2 production.

I've decided to replace the oil cooler and while looking into what that involves, it's possible I've the oil filter / cooler bracket from the MK3 fitted.

It has a slightly different profile to the images of MK2 ones I've found on-line, plus an extra threaded hole which is blanked off with a bolt. Two of the holes accept the oil temp. and oil pressure senders.

I already think the car has a MK3 fuse box and I'm pretty confident the bracket and it are both original to the car, not added later.

I obviously can't confirm anything, but it's a plausible explaination there was cross over of interchangable MK2 / 3 parts in that final period.

Anyhow got me wondering just when my car was actually made as opposed to registered.

I don't have a factory / museum certificate which would probaly save all the hassle, maybe someday but they're quite expensive, so have tried to work it out for myself.

I did this years ago for the MK1 and from what I can remember of that the MK2 data sticker is just an evolution of the earlier cars and presumably can be deciphered in much the same way.

If you look at your data sticker in the boot the very top line will start 1222 (or similar) then a break followed by a series of numbers in this format -

35-5-0226 (mine)

The 35-5 part is what you're after.

35 is the production week and 5 the day of that week.

In my case we already know it's a 1991 car, not to be confused with model year, (which for me is 'N' - 1992) and I think run between 1st August and 31st July each year.

The production weeks are calculated from January 1st of each year and the days of the week run from a Monday to Sunday.

There's on-line calculators that'll tell you the week numbers for a given year, for me week 35 of 1991 commenced Monday 26th August and ended Sunday 1st September.

If Monday 26th is day 1 then day 5 is Friday.

This should mean my actual build date was Friday 30th of August 1991.

I can't find a definitive reference that states when MK2 production ended, the closest is on VWHeritages history of the MK2 who just say in October 1991.

Rubjonny has an old post on ClubGTI where he says the final chassis number was 300000.

Mines approx 225000 short of that - is it possible they could have made that many during September and October, worldwide maybe?



  

 

Mine's still the original and visually seems to be OK, but a bit grotty and getting old.

Was checking to see what a replacement one would cost and prices are all over the place, even for the same brands if you don't shop around.

If you're with Amazon Prime they're doing a Febi Bilstein one for £12.38 including postage which can't be bad, even as a spare... see some on eBay looking nearly £60.00 for the exact same thing, mad!

Checked the Febi on-line catalogue and despite what Amazons own part suitability says 14550 is definitely listed for the 1.8 8v PB engine  - no worries though, there's free return postage if I've somehow got it wrong.

Doesn't seem to have a seal included but they're small change, Heritage even do one for £2.00.

Cheers guys! Interesting. It does store the settings, think I’ll take that as a win and ignore the ignition issue (there is a wire plugged into that slot on the back of the radio but clearly it’s not doing much)

Guess I’ll take the risk on the flat battery thing! Wonder how long before that catches me out, sweepstake anyone? 

Hi all,

I’ve got an old Blaupunkt radio in my 1986 Golf Gti and it doesn’t turn on/off with the ignition, I just turn it on and off at the unit each time. Does anyone know if this is normal on this age of Golf?

Curious if it’s a fault or if it’s just how they come! Lockdown must really be biting... 

Cheers
Will

If it's possible, go back to your FAE sender, it was 5 Bar and fit it at the point above the oil filter to see what readings you get.

Different engines I know, but to give you an idea - The 205 has a factory 5 Bar gauge and is on its original sender so presumably 5 Bar compatible and giving as accurate a reading as factory gauges will allow.

At idle on cold start up it will be showing around the 4.5 Bar mark before eventually dropping to around 1.5 Bar when fully warm.

If you look at the specs for senders on the VDO webhop site it'll show the measurement ranges for 5 and 10 Bar senders which'll give you an idea of the differences.

If I've understood correctly they work by using resistance, measured in Ohms.

Most VDO gauges seem to work between 10 Ohms and 184 Ohms... if you're using a non-VDO sender with a VDO gauge you'll have to ensure it works between this same range.

Below is listed the 5 Bar senders ohms readings beside the 10 Bars - it'll show how using the wrong sender / gauge combination can affect the gauges accuracy.

Oil pressure is 0.0 Bar

11 + 10

Oil pressure is 1.0 Bar

47 + 31

Oil pressure is 2.0 Bar

82 + 52

Oil pressure is 3.0 Bar

117 + 71

Oil pressure is 4.0 Bar

151 + 90

Oil pressure is 5.0 Bar

184 + 107

The 10 Bar sender will continue in 1 Bar increments to its max as follows -

6 Bar 124
7 Bar 140
8 Bar 156
9 Bar 163
10 Bar 184

If your engines true oil pressure is 3 Bar your 10 Bar sender is giving the gauge a measurement of  71 ohms instead of the 117 ohms a 5 Bar sender would be so it'll be under reading by about 40%.

Is it a 10 bar sender and your gauge is to 5 Bar?

Modern cars are missing a trick not fitting (useful) gauges, just adds to the pleasure of owning / driving plus helps avert a mechanical mishap before it happens.

Did you fit the new oil pressure sender to the lower point above the oil filter or the upper point on the end of the cylinder head?

Good news... what turned out to be the issue?
