The OEM FRP is 4 bar, and sits on the right hand side of the fuel rail - from your picture it looks like right location and clip, but there should only be a very small vacuum host attached to a nipple, not that big hose.

To remove it, take out the clip and use plumbers pliers to gently rock it out - use some silicone lubricant or penetrant spray first - but don't lever it with a screw driver as the circular housing is very soft metal and can deform easily. I guess if you are replacing, it doesn't matter too much if you damage the old one a bit.

Currently has an aftermarket FRP fitted.

I have ordered a oem bosch one that should be here tomorrow. 

Does the thin vacum you mean go from FPR to vacum on inlet?

So the current "blank" should pull out with some persuasion?

Thanks 

Hi all,

My mk2 runs a abv corrado engine and its currently has an aftermarket adjustable FPR, that has started making what I can only describe as I tingling noise on ignition!

I'm going to replace with an oem FPR. 

Is it a blank where the oem FPR would normally go?

Also I pryed up the clip, it spins but did not want to come out!!

Any tips of removing this and how best to fit a oem FPR would be really appreciated. 

Thanks

try opening the next page in a new tab, that usually works

Still not working.

I'm not clued up on electrics so really looking for some help and possibly someone who could make the loom up for me to use 2 x 10" fans utilising the oem fan wiring and control module.

If anyone can help, please PM me.

Thanks

You may have to stick /page/2 on the end of the address bar (an annoying known issue on here...).

Still doesn't let me view..

Have a read through this thread chap

 

Hi, I cannot see past page 1. ☹️

Is there any anyone who can make a loom up for me, so I can use original fan loom and controller to operate slimline fans?

Thanks 

Hi,

I have a mk2 golf running abv engine /loom.

Is it possible to use the oem fan wiring/ control module with slimline fans?

Anyone used this setup?

Any advice / help would be really appreciated. 

Thanks

RPMs on tachometer yet?

 

no crank position to ecu and the pump won’t run beyond priming

Yes,  rpms on clocks once it fires into life.

Do you know what wire/ plug in fuse box I can check?

I think its just the CP suffix ecus with the built in immobiliser, not AG, although those symptoms you describe are very much immobiliser type issues

So AG definitely does not have an immobiliser?

Would the fuel pump prime at all though,  if it was an immobiliser issue?

I'm going to go through the loom again tomorrow as I think it may he a fuel pump wiring issue...

Hi, does any know if ecu 021 906 258 AG has an immobiliser?

Changed loom today and it fired up, but then cut out.

Fuel pump also sometimes primes and then other times primes and stops after about 2 seconds.

thanks

To the right of the intake manifold is the plug for the injectors. Put a multimeter to the feed end and turn the engine over. You should get a voltage pulse. If you don’t then you know it’s an electrical issue (affecting the pulse) down stream from the injectors.

Thanks James.

On closer inspection today its come to light the loom is a complete mess and missing some wires in g1plug that are from engine harness 😫

Any anyone has a 6 pin maf engine loom available,  please pm me!

Thanks again all for you respective inputs.

Are you getting voltage at the injectors ?

This may help your relay locations:

 

How / where would I check for volts at injectors? 

Any guides on how to check this?

Thanks 👍🏼

Yes. Starter spins strongly. 

No movement on rpms when cranking.

So more issues uncovered today!!

Relay 109 has arrived and hasn't made a difference 

Ive checked resistance between pin 1 and 2 on cranck sensor. Reading went up and down from 12 - 16 but then held at 0.85

I'm a complete novice went it comes to electrics so please go easy on me!

I've unplugged the ecu and checked for perm live at pin 54 and nothing!

I have 12v with ignition on at pin 38.

Also strange one, with the ecu unplugged, ignition on, the fuel pump buzzes!!!!!!

Really not sure where to go from here!

What's the back story, has it ever run? Bought as a non running project?

 

What ECU is fitted, part number? Golf clocks could mean ECU could be OBD1 dizzy, OBD1 coilpack or OBD2 coil pack.

 Dizzy will be Pre immobiliser, OBD1 / 2 with coil pack will be immobilised from the factory - immobiliser intact and need a transponder key coded to match, or ECU de immobilised previously (usually written on the ECUs cover in marker pen - maybe?).

Hi, back story is it was running but was parked up after radiator gave way c2017.

Bought as a non running project. 

ECU part number is:

021 906 258 AG

0 261 203 108/109

As far as I know its obd1, as from what I've read all abv corrado engines are?

It's running a coil pack

Any help to get it up and running would be really appreciated 🙏🏼

Ahh if no 109 then you have no ECU control so that is probably your spark issue.

With regards to testing the coil pull a lead and insert spark and crank - check for spark. However wait until 109 is installed.

I'm unable to upload a pic for some reason buy I've just checked what relays are plugged into the fusebox, as below. 

1 - nothing

2 - 72

3 -nothing atm, waiting on 109

4 - 18

5 - nothing 

6- nothing 

7 - nothing 

8 - 99

9 - nothing 

10 - 53 upside down

11 - 53

12- 80

Do you have spark but no fuel (plugs not wet)?

Relay 167/67 is the fuel pump. 109 is the ECU. When you turn on ignition can feel/hear any clicking on those relays?

You can bridge relay 167 location to make the fuel pump run constantly on ignition (or use a relay 100 in its place to achieve). 

No spark unfortunately. And plugs are not wet either. 

Relay 109 was missing,  so this has been ordered and should arrive tomorrow. I'll check other relays too.

Reading this thread makes me think I should also check coil pack,  but not sure how to go about this!?

could anyone point be towards how best to check coil pack and rule it out?

Thanks 

Also ordered new 109 relay, which should arrive tomorrow!

It's a mk2 golf running abv corrado engine/ loom with mk3 clocks!

No movement from rpm tacho when cranking. 

From reading this thread, I think I need to test coil pack to rule it out.

New to vr6 world so could anyone advise how to go about testing the coil pack please?

Thanks in advance

Did you buy the car as a non runner?

 

A faulty crank pos sensor will give no spark or fuel.

Do you have fuel at the rail?

Are the spark plugs wet with fuel after cranking and removing them quickly afterwards

I am currently having issues with car cranking but not firing up.

I have fuel pressure and can hear pump priming on ignition. 

I removed plugs after cranking and plugs are not wet!

Does this point towards crank sensor?

Hi all.

Does anyone know the part number for radiator switch please?

Thanks
