Mass Airflow sensor throw check engine light needed to be cleaned
plastic intake manifold
actually my second waterpump/thermostat replacement within the year. TBS on the part, finally got a revised part. intake manifold, flap actuator
Water pump leaked and replaced under warranty
Water pump leaking coolant. Replaced water pump.
Intake Manifold i nternal flaps broke. Common issue with VW GTI. Intake manifold was replaced free of charge. Vehicle is under warranty.
Intake manifold failed causing lack of vacuum. Intake manifold was replaced.
failed pressure diverter valve replaced and chain case gasket replaced (oil leak detected)
Coil pack failure. This is the second coil pack to go. Dealer said once the first goes, the rest usually follow within 12-18 months.
intake manifold needed to be replaced, valves had carbon build up so that was not covered under warr. and elected to have that cleaned.
HPFP failed. Car randomly died.
Symptom was low coolant. Found bad water pump. Replaced under warranty.
Replaced failed (leaking) water pump.
Leaking water pump replaced - recall
High pressure fuel pump failed
Installed "clip" on wastegate actuator rod to eliminate rattle that could be heard between ~ 2k and 3.5k RPM.
Replaced intake manifold under warranty after check engine light came on. Dealer noted "intake valves have excessive carbon on them", but would not clean them unless I agreed to pay for this this. I refused, as I see this as a VW issue.
Radiator developed small pinhole leak, radiator replaced under warranty
Change water pump due to leaking coolant. Car randomly dies and cannot restart.
Water pump and gaskets replaced
The random dying, trouble restarting was never fixed. They could not duplicate problem.
Faulty fuel pump had to be replaced
Leak Detector broken
Timing chain tensioner bracket broke causing timing issue & misfiring on all cylinders
Check Engine light on with code P0299 (Underboost). Problem was Overrun Cutout valve (also called Diverter valve) rubber diaphragm ripped causing boost leak. Shop replaced part with new design part that does not use a rubber diaphragm.
Replaced turbo under warranty as a preventive maintenance item due to wast-gate issue (rattling)
Car had a code for bad thermostat and temp gauge was moving funny. Brought car in and they replaced integrated water pump/thermostat under warranty.
4 coil packs replaced.
Check engine light came on, indicating a problem with the cooling system. Initial estimate for thermostat repair was $500. System was leaking at water pump, making repairs warranty-eligible. Woohoo!
Water pump leak found, replaced water pump. Misfires on cylinders 2 & 3, injectors replaced
Water pump failed for the second time.
Camshaft failure coolant pump leak
The timing belt tensioner was defective causing the timing chain to rattle. The clip and chain where replaced under warranty.
"Low oil pressure. Do not exceed 4000 RPM" was displayed on dashboard. Dealer could not replicate the problem but changed the oil filter. Dealer speculated that the valve in the oil filter was faulty.
Hard start and loss of power due to intercooler icing. Wanted to apply VW TSB for issue, dealer refused, "unable to reproduce" (problem arises under very specific conditions)
Hard starts when cold due to intercooler icing/water ingestion from melted ice. Well-documented problem with Mk VI TDIs
Car would occasionally lose power at approx. 3000 rpm during vigorous acceleration. High-pressure fuel pump not performing to spec. HPFP replaced. Not covered by powertrain warranty. Complained, VW paying 2/3 of cost
Car occasionally and suddenly loses all power at 3000 rpm during acceleration. Car still in the shop, VW unable to diagnose issue (HPFP changed in June for same issue-repair unsuccessful). VW HQ involved; 3d attempt to solve issue.
Hard start in near freezing conditions, power loss. Dealer found intercooler hose choked with ice. TSB already carried out did not cure problem. Removed air intake duct to draw intake aire from engine compartment instead of outside.
Exhaust flap failed, check engine light on. Fixed under VW TSB and extended warranty for the part
Bad fuel injector
Car would not start when it was hot. Check Engine light and ECP error all illuminated. Problem solved by replacing ECM and exhaust flap. Covered under warranty.
Emissions light illuminated. Exhaust flap failed; replaced under the extended warranty.
Diagnose and replace intercooler with redesigned cold weather model. Currently condensed water pools in intake, leading to MIL and limp mode. Parts on order; should arrive in 5-6 weeks.
Intercooler replaced with a cold weather model incorporating a bypass to prevent ice buildup under near-freezing conditions.
Engine had hard start. Inter cooler filled with water.
glow plug died, after only 24K miles. Since I was passed the 3 year warranty limit, I had to pay 100% out of pocket.
Exhaust actuator valve stuck open
Check engine light came on and exhaust gas temperature sensor #3 gave erratic signal and needed replacing. Not covered under warranty because more than three years since purchase ;may dispute. Update: dealer later refunded $460 labor charge.
ECU light diagnosed as throttle valve electrical connectors; ECU came on 3 weeks later and advised throttle valve needed replacing. VW picked up 50%; remainder covered by good will package.
Rattling noise coming from turbo wastegate under acceleration. TSB for the problem was available. A clip was installed that fixed rattling noise.
Leak developed at the water pump. Replaced water pump, all o-rings on pipes. Recall on item pending, will get reimbursed when issued.
The vibration that comes from the turbo when accelerating thru 2K rpm's needed the clip installed. Done by the dealer at no charge, fixed the vibration noise. I noticed it, read about other cars having it on the web, asked dealer and they knew of the TSB.
The water pump was found to be bad. My temp light indicated the coolant might be low and I should check the maintanance hand book. After looking I noticed all of the coolant was gone from the resaviour so I called the dealer right away.
Engine rattle which has no fix as of yet per Volkswagen North Scottsdale (TSB 211001). "Silenced by more than 50%" but is still present.
Engine vibration/rattle when accelerating between 2,000-3,000 RPM. VW released a TSB over the summer of 2011 to attach a small metal clip onto an engine component. The rattle/vibration is nearly gone, just barley audible now.
Radiator failed and leaked coolant
Engine leaking coolant, filled it leaks out every month
Engine was leaking coolant badly.
Coil pack failed causing engine misfire in one cylinder. Replaced faulty coil pack and normal operation resumed.
slight stumble noticed in idle. Flushed fuel system and replaced spark plugs.
CEL came on and code P2015 was pulled. Intake Manifold Runner Flap was stuck in the open position. VWoA extended the warranty to 10yr/120k miles to cover this defect.
Misfire cylinder 4
Engine misfire. Coil pack replaced
Check engine light. Low high side fuel pressure sensor.
Oil pick up clogged. Engine needed replaced. All regular maintenance followed to a T prior to failure.
Oil leak around lower timing chain cover.
Intake manifold flaps were broken, resulting in illuminated check engine light, replaced entire intake manifold. Wastegate rattle at low revs under load (heavy throttle). Replaced wastegate actuator rod clips per TSB.
Check engine light came on, scanned and pulled code P2015 - Intake manifold flaps. Dealer replaced intake manifold at no cost under VW's extended warranty (10yrs/120k miles) for this part. Second time it's been replaced.
CEL came on. Took car to dealer. Faulty part related to turbo intercooler was fixed. Loose passenger door was also fixed.
High Pressure Fuel System (HPFS) failure. Was covered by VW out of warranty, but normally is approximately $4,000 Replaced water pump due to slow leak. $318.00
4th Time back to fix CEL. Replaced ECM (computer), Diesel Particulate Filter (2nd time, 1st time was at 14,500 miles approx) and Valve flap as part as a recall or tech bulletin. Est. parts and labor to date is just shy of price of car.
