All that said though, I am personally not a fan of fitting modifications to try and solve problems where it is unclear what the source of the actual issue is. As above the first thing to check is whether this is boost control pipework glugged up with oil. If it is, check and see if it's the obvious cause. If the oil level's not the cause, move forward from there.
I dont want to introduce more problems by fitting a different part.
(Are Boost Solenoids commonly perishable?)
I'll nip out at lunchtime to get some break cleaner and re-clean the Solenoid. I'll check the oil leve after getting back (so nice and warm) and let you know what it's looking like.
(Thanks for your help fella, it's been invaluable to me

I had this problem on my bugeye and cleaning the solenoid helped but didn't fix it.
I ended up adjusting the arm that connects to the turbo to adjust the wastegate. That fixed it.
I hope that helps

sounds exactly like the problem I am having on my uk 98 is it easy to clean the solenoid also think my oil is overfilled only got the car last week as well. Anyone in the Coventry area able to give me a hand trying to fix this I have no clue with it at all. Mine also seems to be fine when it is cooler but really jerks around when it is warm was yours like that? Sorry for jumping on your thread mate.
cheers

Hi guys,
I've not yet had a chance to check the car any further... I'll do it tonight and will let you know the outcome of oil level etc.
Matt,
From what I learned, the Boost Solenoid is very easy to clean once you have found it! (I have filled it in with Red to highlight it, Below)
Assuming it is a 2 port solenoid it will have 2 x hoses going in to it. Remember where these go. I know there's only 2 hoses but it's a good idea to mark them just to make sure!
Ok, under the dashboard drivers side, below the steering column you will find 4 connectors: 2 x Green, 2 x Black.
before you go any further, familiarise yourself with http://www.scoobypedia.co.uk/index.p...gECUCodes#toc2 so that you can read the fault codes (if any).
Anyway, with the car turned off, connect these wires together. Your car will now be in Diagnostic mode. Turn on the vehicle's ignition (dont start the car). You will hear all the relays clicking in and out and the fan cutting in an out. Make a note of the check engine light flash codes - if there are any.
Once you have connected the wires it is time to clean the solenoid.
Get yourself a can of brake cleaner. Remove the tubes from the solenoid. You may have to unbolt the solenoid to do this. (You should hear it clicking on and off). Squirt cleaner through the solenoid. It will run out of the other side. Keep cleaning it until the cleaner runs clear i.e no dirt comes out. I found it helpful to have a cloth or some tissue paper to catch the cleaner when it runs out. This makes it easier to see if it's bringing any contaminants out. Remember that the cleaner may be flammable depending on which cleaner you choose so take relevent precautions.
Once the solenoid is clean, it's a good idea to clean out the pipes that attach to it. Remove these 1 at a time so you remember where they go and flush with cleaner until they are clean.
Re-assemble everything and you should be good to go.
Up to you if you want to do an ECU reset - details of which you will find in the Scoobypedia. Disonnect the wires and away you go.
It's a simple 15 minute job the first time you do it.
Good luck.

Hi Splitpin (and sorry again for the long time to respond). Ive been working a lot the last month and wont be online all next week either.
However, I have checked the oil level and it appears its a little high. Hopefully this is the cause. I will drain a little out so that it goes to the correct level.
I've not used the car for a while but want to get it all sorted as am considering a track day at Snetterton on 8th October along with a freind in their Scooby (which they bought purely for track days).
