Go and see Jaba.

Get a VR6 tank and pump as the Corrado VR6 always used a 4 bar in tank pump and that will be perfect for what you need. Just make sure some Nelly hasn't fitted a late Golf VR6 3 bar pump as that is quite common.

So you disconnected the head switch but what about the rad switch? If you did that as well, you will have a faulty fan control unit, that rectangular box under the expansion tank.

Can you get a fault code read done?

Possible, but the G60 used a fuel pump run on system to circulate cooling fuel into the rail. It may be that it was difficult to provide a 5 bar suitable coupling on the sender top unit down to the accumulator, who knows what the reason was-it would be interesting to find out. I remember getting into a heavy discussion in Autocar mag a few years back about whether the Beetle ever had a folding rear seat and just as it got acrimonious, a chap who was on the design team in the early 60's jumped in to back me up in saying it dis have a folding rear seat. I suppose the German forums get some people going on them who are/were involved in design at Wolfsburg, a shame we don't.

I make my own ridgid pipes using a Sykes Pickavant ( http://www.sptools.co.uk ) flaring tool, a propriety pipe cutter and Kunifer10 (90% copper, 10% nickel) pipe and M10x1 male steel ends, easily available from any local motor factors in rolls and boxes respectively. Brass ends are available but I find they can chew their threads very easily so we use plated steel ends with ally paste inside the end on the outside of the pipe and spray wax over the top to prevent corrosion induced pipe twisting in years to come.

Early G60's had two pumps but all post 90my electronic injection models had one in tank pump but as Supercharged says, the K-Jet models need them both. We can't undo VW's engineering with wishful penny pinching, if VW decried that the system needed two pumps you can be sure they didn't do it lightly as their accountants are far more critical and nit picking than any of us.

The most common cause of this is a faulty distributor, new from VW they are less than £100.

No, the system needs 5 bar and the only HP in tank pump runs at 4 bar. Why would you want to do this anyway? If it could be done, the bean counters at VW would have done it.

Huh, light weight!

I don't think you can get them pattern but used can be OK and new they are expensive from VW.

12-mm. New nuts are N 902 002 01.

There isn't much info on the Corrado with the 9A engine readily available. If it is engine management info you need, Robert Bentleys “Volkswagen Scan Tool Companion - 1990-1995”, ISBN 0-8376-0393-5 has a section on the 9A’s diagnostic capabilities that is quite useful. For further information, the same authors “Volkswagen Passat Service Manual: 1990-1993, including GL and Wagon”, ISBN 0-8376-0378-1, should cover everything else you need, as there are many synergies between a B3 Passat and a Corrado.

The KR accumulator is 431 133 441 C and the 9A is 447 133 441 so no. It should not be difficult to find one new or used but they hardly ever fail, the only problem we get with them is rusting through and leaking.

The rear pipe (the brass one if I remember) goes to the vacuum feed hose for the servo and the other hose goes to the air cleaner hot air flap unit that ducts hot air from the exhaust when required. The orange unit is a temperature sensing vacuum proportioning valve and they often leak.

The coolant lost from the bottle has damaged the fan control box under the water bottle. I have seen a number of cars catch fire due to these getting coolant in them. VW realised (rather late) that it was a stupid place to put the unit and on other models it is in a more sensible place.

They will fit but the spring rates will be a little too low as the Corrado is heavier.

Whatever the mixture going into the combustion process is, the lambda sensor will alter the fuelling to achieve lambda one if it is within its trim window. You need to get a fault code scan and a pre cat sniffer port gas reading to see what the pre cat mixture is. If it is around lambda one and you have no fault codes, you have an inefficient cat which usually responds to a good thrashing prior to the test. If it doesn’t respond, you need a new cat which isn't uncommon on the 9A as they use a little more oil than is healthy for cat longevity.

That is an odd choice of cable but the part number is 6K2 721 335 F and costs £36 ish from Seat.

OBD II is defined as an engine with a post cat lambda sensor.

The front top mounts don't come fitted.

Those H&R's are great and the KONI coilovers give an unbelievable (for coilovers) ride quality.

Ohh you would not believe the things we see. About a month ago I had a G3 VR6 come in with Hicon TX's on that had started leaking on both sides at the front and these were replacements for the originals, all in the space of six months. When the replacements had started leaking I insisted on seeing the install for myself. What they had done was unreal. The special VW machined nut (PR 2E1 systems only) in the middle of the top mount was underneath the top mount and the top mount then bolted down on top of this with one of the two half nuts provided for the engine bay top plate and the top plate only secured by one of the nuts. This meant the top mount did not rotate with the steering so the rotation was made inside the damper and therefore it was lasting weeks, not years. On other cars I have seen dust shields over bump stops that were then fitted upside down, spring plates upside down, camber set positive instead of negative, front springs plates missing altogether with the springs straight into the top mount-you name it, I have seen it done. There are some complete morons out there, some are garages as well. Since including detailed kit specific instructions with every single Weitec kit we send out, warranty problems dropped from being a pain in the butt to virtually zero.

Nothing wrong with competition no, but price wars only end up with a devalued and cheapened product.
