    5th Gear upgrade

    LOL.... 5th gear upgrade if you bought the gears would cost £300 ish. If you get on the T4 and T5 forum a set of std gears would probably cost you £50 as lots of van owners upgrading and the std ones from my van were just the right ratio. A reminder that you can do all of this with the gearbox...

    5th Gear upgrade

    Well I had to replace the clutch on the A3 (slipping) so while the box was off I swapped the gears. Much much nicer now on the motorway and I can still bimble along in 5th at 40-45 ish. Replaced the rear crank seal while the flywheel was off. Loving this car ! only paid £650 for it just over...

    on board computer read out blank

    Thanks all, feeling a bit stoopid . Quick press of button had it back on. The long press clearly doesn't do anything other than reset the computer. Not sure why you would want to turn off the display ? I still blame the wife for fiddling with it.

    on board computer read out blank

    Cheers, I did try that, but possibly didn't hold it on long enough. I'll try again and report back. I blame the wife !

    on board computer read out blank

    I have an S reg A3 1.8T and noticed today that the little screen is blank. Seems to have coincided with a bulb warning light coming on but probably in related. I have a sneeking suspicion this display can be turned off ? Anyone know why it might have gone off ?

    AGU ECU remap or immobiliser delete

    I have a slight problem. I have installed an AGU engine in my T4 Van. I had the ECU (06A 906 018 AR) remapped and immob deleted. All worked well but I'm having trouble with the emissions. I also have an AGU engine A3 (I loved the donor car so much I bought one to run around in) this has an...

    Limp mode caused by oil pressure sensor ?

    Thanks Tufty, I did a bit more research last night and found those links. But it seems a little unclear how to fix it. Do I need Vagcom or VCDS or VCDS Lite. Or will leaving the ign for 3 minutes do it. Obviously I guess it might be worth giving it a clean before I do all this save having to...

    Limp mode caused by oil pressure sensor ?

    Hi, I;m getting error codes 17967 17973 both I think are linked to the throttle and I had assumed were to do with the fact that the cruise control that the donor car had is not wired in. I also get 18259 which is ABS which of course the van doesn't have. The ECU has been mapped/chipped so I...

    Limp mode caused by oil pressure sensor ?

    As it says, I have put an AGU in my T4 and I'm struggling to get boost over 3psi. I have some error codes but none relating to oil pressure. I know the A3 ECU is not wired up to the oil pressure sensor. Would that cause limp mode ? Surely I'd get an error code for lack of oil pressure ?

    5th Gear upgrade

    Yep, I believe a smaller turbo spins up quicker and gives a bit more torque at the expense of power.

    Smokey AGU engine

    I have just fitted an AGU engine into my W T4 van. I had a donor car which I used for a few weeks. Now the engine is in the van it's smoking quite bad, not so nad after a run though in fact I'd say no smoke. Given that I still have a few things to wire up is there anything that could cause...

    5th Gear upgrade

    As far as I know it's all standard. I have a boost gauge and it reads up to about 7-8 psi. And it's an A3 not an S3

    5th Gear upgrade

    well no more than you're driving at 70. But seriously mine pulls like a train from 2000 rpm.

    Loads of info on swapping the gears on the T4 forum.

    5th Gear upgrade

    Well in case anyone feels like me the gears I'm going to fit are 34 teeth and 45 (ratio 0.756) originals are 36 and 43 (ratio 0.8372) This should give me a road speed of 77 mph instead of 70 if I've done my sums right ! If anyone wanted a set of gears they are on ebay or go on the T4 forum and...

    5th Gear upgrade

    No it's a 1.8T , I just have a thing about revving an engine over 3000 on a run. I absolutely love this car apart from the cruising revs. I think they design these cars to go 70mph with 4 people and luggage towing a caravan. So running with 2 people should be easy at a higher speed. Same...

    5th Gear upgrade

    OK 70 at 3000 rpm does offend me. Takes about 90 minutes to change the gears which I have anyway. So a lot easier than swapping a gearbox. Just seem to me that the engine could pull a higher gear. As I said I did it on my gutless heavy van and it's fine. Just to be clear all you have to do...

    5th Gear upgrade

    Has anyone upgraded their 5th gear. What I actually mean is change the ratio. On the T4 forum it's a common mod to change the 5th gear ratios and raise the road speed you do at a given revs. My A3 1.8T currently does 70 mph at 3000 revs and to me this seem too high revs for that speed. My...

    K03 turbo shaft play

    Buying a secondhand turbo is always a risk especially as refurbed K03's are relatively inexpensive to buy these days.. Depends on how much it owes you but I would at least start a dispute on eBay to get a sizable refund to mitigate the rebuild <tuffty/> Where's a reliable place to get a turbo...

    rear suspension knock

    I had a look at the bushes and although I'm no expert they didn't seem too bad. Have to admit I didn't look at the springs. I guess if it is the bushes it means dropping the rear axle or is it possible to do one side at a time ? Also I guess poly bushes are available....Bit expensive but so...
