*Resolved* Engine Not Revving Under Load

« on: February 15, 2017, 09:29:06 pm » Had the car off the road for 5 months with the battery disconnected whilst I was in the FalklandsJust back now and have started the job of putting the car back on the roadWhen I connected the battery initially I had the usual Traction Control, Tyre Pressure Sensor and Air Bag Lights on which I solved by rotating the the wheel to the left and right for 5 secs and driving slowly forward which cleared all the dash lights and all was good.However - upon taking the freshly taxed GTI down the road after a good wash and polish when attempting some spirited acceleration the engine seems to be suffering with a fuel cut situation, no dash lights or check engine lights though.With gentle acceleration it drives fine and have just put a fresh tank of super in however under load it wont rev - gets to about 3k rpm and cuts the engine back to idleThis evening a good friend came round and we scanned the car, below are the results of the scan Obviously the engine speed sensor and low pressure fuel sensor are showing a fault however would the first issue of power supply low at terminal 30 cause all the reported issues? Any help greatly appreciated - car was working perfectly before I went on "holiday" and would rather sort the issue myself rather than paying for the rectification to be carried out Wednesday,15,February,2017,21:08:25:41182VCDS -- Windows Based VAG/VAS Emulator Running on Windows 7 x86VCDS Version: 17.1.3.0Data version: 20170203 DS267.2www.Ross-Tech.comVIN: License Plate: ---------------------------------------------------------------------------------------------------------------------------------------------------------------- Address 01: Engine Labels: 06F-907-115-AXX.clbControl Module Part Number: 1K0 907 115 Q HW: 8P0 907 115 B Component and/or Version: 2.0l R4/4V TFSI 0020 Software Coding: 0403000318070160 Work Shop Code: WSC 00132 210 81461 VCID: 34675AB6579BB1E13D-80604 Faults Found:001089 - EVAP Emission Control Sys P0441 - 002 - Incorrect Flow - Intermittent Freeze Frame: Fault Status: 00100010 Fault Priority: 2 Fault Frequency: 1 Reset counter: 255 Mileage: 282888 km Time Indication: 0 Date: 2000.00.00 Time: 07:33:54 Freeze Frame: RPM: 839 /min Load: 19.6 % Speed: 0.0 km/h Temperature: 69.0∞C Temperature: 26.0∞C Absolute Pres.: 1010.0 mbar Voltage: 14.224 V005634 - Power Supply Terminal 30 P1602 - 002 - Voltage too Low - Intermittent Freeze Frame: Fault Status: 00100010 Fault Priority: 2 Fault Frequency: 1 Reset counter: 255 Mileage: 0 km Time Indication: 0 Freeze Frame: RPM: 0 /min Load: 0.0 % Speed: 0.0 km/h Temperature: -40.0∞C Temperature: -40.0∞C Absolute Pres.: 0.0 mbar Voltage: 0.000 V000801 - Engine Speed Sensor (G28) P0321 - 008 - Implausible Signal - Intermittent Freeze Frame: Fault Status: 00100010 Fault Priority: 2 Fault Frequency: 1 Reset counter: 255 Mileage: 0 km Time Indication: 0009529 - Low Pressure Fuel Sensor (G410) P2539 - 001 - Open Circuit - Intermittent Freeze Frame: Fault Status: 00100001 Fault Priority: 2 Fault Frequency: 1 Reset counter: 255 Mileage: 284526 km Time Indication: 0 Date: 2000.00.00 Time: 14:29:18 Freeze Frame: RPM: 1203 /min Load: 32.5 % Speed: 0.0 km/h Temperature: 18.0∞C Temperature: 10.0∞C Absolute Pres.: 1010.0 mbar Voltage: 14.224 VReadiness: 0000 0000 « Last Edit: February 24, 2017, 12:34:44 pm by StuF » Logged Where Napoleons armies marched with horse and musket and Hitlers Reich crumbled in blood and rubble, the warriors of Armageddon do battle against the landscape of hell now indeed thrive the ARMOURERS

Was it mapped? Maybe it needs a hpfp and corresponding components? Logged

Engine is standard and nearly on 180k so doing wellRich - yep gets to about 3k and the gauges just drop and die flicking back and forth Will nip out to get a crank sensor and report back Logged Where Napoleons armies marched with horse and musket and Hitlers Reich crumbled in blood and rubble, the warriors of Armageddon do battle against the landscape of hell now indeed thrive the ARMOURERS

That is basically the main battery supply to the fuse box and if the battery goes flat, or disconnected whilst doing work, it logs it as a fault. Logged 2007 ED30 | 2009 TDI 140 | 2016 BMW 330D

« Reply #6 on: February 16, 2017, 11:20:31 am » Thanks again for the reply'sIs this the correct replacement item - dont really want to drive the car till its sortedhttp://www.ebay.co.uk/itm/VW-Golf-MK5-2-0-GTI-Genuine-Lemark-Camshaft-Position-Sensor-Replacement/361507684823?_trksid=p2047675.c100010.m2109&_trkparms=aid%3D333008%26algo%3DRIC.MBE%26ao%3D1%26asc%3D41415%26meid%3De9e8d11b8bd5439e9b92f17e6195fcb5%26pid%3D100010%26rk%3D1%26rkt%3D6%26sd%3D291788396185Im guessing its a straightforward swap?Shouldnt the low voltage terminal 30 dissapear now the battery is charged and reconnected These faults were recorded after clearing all the old ones? Do you think it is worth replacing the low fuel pressure sender at the same time or is that failing because its getting the incorrect reading from the camshaft sensor?

It's more money I'm afraid!I would only use a dealer one personally. It's a critical sensor and not worth risking a cheapy ebay one.Yeah the terminal 30 error I've had dozens of times but it always stays gone once cleared and it's happy with the voltage. If it keeps coming back with a decent battery, you might actually have an issue that needs looking into. It the battery voltage drops too low during cranking, that can also trigger a fault.Try the crank sensor first, disconnect the battery and touch the terminals together a few times to do a full 'capacative discharge' reset, reconnect, drive it around for approx 20 miles with soft and hard throttle inputs so that it adapts, then recheck for fault codes.

« Reply #11 on: February 21, 2017, 03:38:08 pm » Well I am happy to report that I have today managed to replace 3 of the cars sensors Camshaft Position Sensor - easy takes 5 minsLow Fuel Pressure Sensor - again 5 min job And the Crank Sensor - my god that is a job I never ever want to do again - took me hours and hours! Also replaced the oil and oil filter with some lovely Mobil 1 0w40Went for a 45min test drive and it pulls like a train and revs to the redline like a scalded cat! Successful day all round! Just need my buddy to come round again to clear the codes and Im good!
