Problem seems to be fixed. Passed Car to Electrical/Diagnostic Engineer in Dewsbury that came highly recomended. He rang me this morning to collect car as it was cured. There was corrosion in the wiring loom on the connectors which was causing signal issues from ecu and auto gearbox. have driven car around and it seems fine. no doubt will know over the next few days. hopefully its all sorted. thank you for your input and help. hmk, again thank you.

Ran diag while engine running. Pedal flat to the floor diag showing tb at 95.2 % dash showing roughly 5000 rpm car surging. removed video (saving space), as problem cured.

Hello, FOlks. Hope all is good. I left car as was last 3 days. Started it this morning. Same problem. Ran for a few seconds then died. Restarted and it started was.running for about 29 mins with a rough idle 1000rpm. Press 4he accelerator and the idle drops. Restarted a third time now after running rough for 20mins and it's running fine. Like nothing was wrong. EPC light is in and so is the engine check light. Am going run the scanner now see what comes up.

cool, will look at it again. my shift finishes sunday morning. so will get back on it monday. i have a multi meter somewhere. hmk cheers.

excuse the my spelling, just woke up..

Hello, Thanks for reply. Are we saying the TB is failing? I have put the original unit back in as i was getting the same idling issue with the new TB. its currentlky idling at 1000 rpm . when the accelerator is applied it starts to become erratic . when i change gear from park to drive, the car feels like its been hit from behind like a rear end collision. I have not looked at car agin since yesterday...its too cold and i work nights. Got tired for velectrician to turn up, so ordered vcds. waiting on that now. again, thans for reply. hmk.

Hello 1.4 16v Auto currently being a pain.

I was thinking the same. The new tb when installed did not change the engines idle, it was still erratic until VCD was used to set the basic settings.. The car then ran fine until a 3 days after. going to it put on a laptop with vcd tomorrow. then leave it with the electrician to see if the problem occurs again, so he can work out the problem as it happens. The actuator tests did run without any problems, the throttle flap moved through a range of angles, so did not think there is an issue with the tps/linkage inside the tb. unless the actuator tests run a higher voltage to run the tests? cheers

Ok, thanks for reply. I put car back together. Cleared codes. Using a snap on apollo d8 scanner if that means anything. The codes being returned are: 17989 tb basic setting not performed. 17950 angle sensor throttle motor - g187 not a plausible signal p1542. Again thank you for any help.

These are the codes now original tb back in.

Old one is the first photo.

Thanks for the reply. The tb was was reset using vcd. Not reprogrammed if that makes sense. Because it was replaced. Now been advised by garage to put old tb back in. I am cleaning it now although it's that dirty inside. The new one is a pierburg and the old one is vw ag. gearbox is ok recently serviced. will have to get codes again and will put them up. The egr as stated already is also new.

Not sure if any help, I use this on my lupo, https://www.halfords.com/cycling/bike-racks/rear-mounted-bike-racks/solo-single-pack-black-147920.html am assuming you going to carry 2 bikes? if it fits a golf it should fit lupo as they both pretty similar at the back, surely halfords would know? https://saris.com/pages/findmyfit lupo not listed on their site.

I have searched most of the site and no wiser. so asking for help and advice. I have a lupo which is an automatic 1.4 16 v year 04. bought some years ago with only 25k one owner. Had a good few years problem free drining. now on 54k. did regular service and looked after it. last year suddenly the idle went crazy and car was in limp mode. turned out TB failed. got a second hand one which was cleaned and worked care free until a year later. RAC came out and said TB was done. not suprised as it was a used unit. So I got a new pierburg unit installed and programmed in using vag software. a month later same problem again. Again RAC to the rescue. They checked the car over and stated the EGR was failing. they cleaned it on site where i had broken down and got the car going. within an hour,broke down again. So I replaced the EGR with a new pierburg EGR. car was also again reprogrammed and worked fine. Today the car broke down again. luckily i was at a friends garage. As it was cold I started the car and let it idle to warm up, got caught in a conversation and left the care idling. The car was idling for about 30 to 40 mins, when the revs suddenly went up, the car reved high for about 3 mins and then started to idle up and down erratically. now when i start the car it seems top be in limp mode any pressure on the accelerator drops the idle so the car is not really driveable? any advise would be appreciated? thank you in advance. Hoping to get in touch with guys who programmed it tomorrow. again thank you.
