Secondary Air Pump
Engine light came on. VW says I need a new Secondary Air Pump (02 Jetta 1.8T, Auto, 55,000 miles).
Had Catalytic Converter replaced a few months ago.
Both will be covered under warranty (luckily I am near dealer ) but should this be happening on a car with 55K ?
Thought I could keep this car for 100,000 miles but its looking like this isn’t the car for that.

You Bought a Volkswagen – You bought a volkswagen. You have to expect to spend your time at the dealership. It goes with the territory. Bend over and say:” Give me the VW experience”.

Secondary Air Pump – There are vacuum lines related to the secondary air pump that could perish from engine heat and leak. This then triggers check engine lights. Check out all your vaccumm lines, especially the ones closest to the hottest areas of your engine. A perished vaccum line under my VR6’s Passat intake manifold that connects to the secondary air pump system caused the check engine light to go on. Unfortunately it’s in the most inaccessible area of the engine where no human hand can reach it, so it stayed unfixed for the longest time. I just couldn’t get myself to pay the VW service department a likely 100+ bucks just to replace a short run of vacuum line. I tried to fix it through contortions of my arm and body just to reach the offending line, but there was just no way to get at it myself. Even though i have done what I thought were complicated enough things on the car like replacing the serpetine belt from under the car to avoid having to remove the airbox assembly entirely. Man!!! was that such a messy job. Had VW grease stains on my hands for months, no mattter how hard I tried to wash it off!

Secondary Air Pump – My Jetta has always had a very bad hesitation shiting into gears once it is warmed up. Feels like the trans is slipping. Before looking into transmission service thought this may be part of the problem. My understanding is that secondary pump feeds exhaust back to engine to burn off pollutants??? Does it sound feasible that this would cause hesitant shifting?

Secondary Air Pump – Automatic – tiptronic, 1.8 T
When car is warm ( drive for about half hour) it gets very hesitant.
Classic example is drive half hour, pull into bank drive thru or coffee drive thru, put car into park while doing transaction, shift into Drive touch gas and….nothing, then clunks in and drive away. One dealer keeps telling me it’s normal.

Secondary Air Pump – The secondary air pump feeds extra air into the exhaust to ignite unburned fuel that occurs during startup in a cold engine. Since it is only on at startup, this has nothing to do with your shifting problems.
With regard to your transmission — is this an automatic or a manual?

Secondary Air Pump – I know the transmission fluid is “for life”, but you could ask the dealer to check it anyway and, if low, refill. This is an expensive procedure, though, since the unit is supposed to remain sealed (anywhere around $300 total).

Secondary – I decided to see how things went before following up on my Secondary Air Pump issue that I originally posted. Dealer felt that replacing Secondary may help with some of the shifting hesitation issues.
In late July dealer:
Installed SOP Air Pump
Remove and install secondary air injection pump motor
VAS 5051/5052 Fault finding diagnosis
Road Test
Road Test
Set Readiness code
078 906 601 M Pump
Not sure if I was being overly hopeful but initially it did feel like SOME of the hesitation went away. It even seems that gas mileage increased slightly, but then again I changed the air filter too.
After several August road trips I have found that there is still a transmission problem. It really is a pain and I cannot beleive that this is normal especially for a car that a) is supposed to have state of the art 5 speed Tiptronic and b)is a performance or driver oriented vehicle.
I am still under warranty but am not sure if I should take it back to VW again or go to something like AAMCO?
