Background: 2015 (70,733 mi), engine light went on & I brought it to vwhartford. They found fault for system to lean found rear main sela is leaking oil which is causing fuel trim faults. Oil cap is leaking oil & the upper time chain cover is leaking oil but the main oil leak is coming from the rear seal. They removed the trans & replaced the main seal & oil cap ($877). In 2016 (94,999 mi), car failed emissions due to intake manifold. Vw replaced this and it was covered under warranty. Suggestion - to get a carbon cleaning for the valves due to build up ($290). June '18 (118,239 mi): my coolant light went on. Vw said my coolant was not low - water pump was leaking. They resealed valve cover & upper timing chain due to oil leaks. They r and r valve cover cleaning & resealed, installed upper timing chain seals and side of engine block of oil & installed new water pump. I asked if this was covered under the warranty or previous work & was told no. I asked if this would prolong the longevity & was told yes ($1800). 8/19/19 (133,449 mi): engine light was on - could not look at for a couple days, but ok to drive as long as the engine light was not blinking. Result: system lean at idle, breather is leaking air causing hesitation. They installed new breather. Asked if it was covered they said no. Asked if it would improve the longevity of my car, I was told yes ($480). Issue 9/4/engine light went on. This was after traveling for labor day (360 miles). On main st. In whart, the car started to shake & bounce at 2 stop lights. Went 2 blocks home. Towed it - was told timing chain went & it's not covered under the tc recall. Quote - used engine $6500+. Told it was worthless & not worth fixing ($125 for diag) towed the car to another place - they fixed it for less than $3400. I have told vw and vwhart that there is something wrong with this make/model, but I am ignored.
At 37,500 miles the water pump on my vehicle cracked and resulted in loss of coolant requiring tow for replacement of fuel pump on 04/19/17. On 2/28/18 at 42,770 miles a broken manifold plug clip resulted in displacement of coolant temp sensor, again with loss of coolant and tow for repair. Both of these episodes were noted after parking the vehicle following a short city drive.
