    PD170 Replacement Turbo

    Thought I would update. Bought a recon from Midland Turbos in the end @ £350. Seems decent quality, works well. The tech documents suggest you remove the turbo from the manifold, leaving the manifold attached to the engine. Didn't work out that way for me as the nuts were too corroded. Even...

    PD170 Replacement Turbo

    Hey, I need a new turbo for my 2007 PD170 Quattro. My current one is on the verge of death and won't last much longer. I've had a ring around a couple of places and the prices seem quite high at £700-800, I've replaced turbos on other VAG cars which usually come in around £350 for a decent...

    Renewed suspension arms, now ride height too high

    Is the triangular top mount located correctly? I don't even know if this is possible, but are the lower arms fitted correctly, once pointing upwards, one pointing downwards. Are the springs sitting in the cups correctly?

    Are Instructions on Fitting Control Arms Correct?

    Quite a lot of work, all fairly straightforward though. Just make sure you have the right tools to hand before you start. The upper front control arms and rear springs are the only bits that will give you the biggest headache.

    Are Instructions on Fitting Control Arms Correct?

    Must be wrong as every other VAG workshop manual I have seen has said the opposite. Just think about it, if the bushes are tightened in the unladen position that are going to be constantly under excess tension when the car is on it's wheels. I would use the instructions as a rough guide by the...

    Renewed suspension arms, now ride height too high

    All four arms need to be tightened with the weight of the car on them, you will never get access to them on your driveway without a lift. I use a jack and block of wood under the hub to compress into the correct position, If you dont the bushes are constantly under tension and will wear out...

    Renewed suspension arms, now ride height too high

    It will take a little time to settle, doubt it's related to the spring as you shouldn't have disturbed that. Did you tighten the bolts on the bushes with the suspension under compression i.e where the arms would be when the car is on it's wheels?

    Will these fit?

    One of the rear ones looks knackered, you would expect them all the be fully extended, unless they were leaking.

    Audi S4 (B7) Vibration from Front Wheel Turning Slowly - PLEASE HELP!!

    All Quattro cars do it to a certain degree, does it feel like it is skipping slightly. Tyres make a difference as does wheel alignment and the condition of the control arms. Aux drive belt/tensioner/alternator clutch pulley can also cause similar vibration.. I've had all of the above with my...

    4-wheel alignment

    The rear is adjustable, via two concentric bolts. This should be set first them the fronts calculated from that.. Regarding the settings used it won't make any difference.

    Lemforder any good?

    May also be worth looking at the Febi Bilstien complete kit, that is around the £300 mark. Very good quality kit.

    Blown Turbo, Stuck EGR Valve or something else??

    They may have had to drop some of the coolant, depends if they disconnected the EGR cooler (above the turbo) or just moved it out of the way. The pulsating on the fluid as shown in the video is from the coolant being returned to the header via the hose at the top, usually you wouldn't notice...

    No power at low rpm 2.0tdi 170

    Sounds similar to an EGR issue I had, PD170 with DPF/EGR mapped out. The EGR valve failed slightly open, I fitted a blanking plate and all was well.

    I had a loss of power on mine just after it had been mapped, turned out the EGR valve that had failed and was not staying totally shut. Obviously you don't get the engine management lights as this is mapped out. Blanked it off with a metal plate and all was good. Might be worth a look...

    Yes it could cause a restriction in the exhaust. There are two bits of mesh, one at either end of the DPF by the way.

    If the DPF and Cat are two seperate bricks within the housing then cutting and welding allows you to remove the DPF brick and leave the cat. The downside is the failure point you have introduced, I guess it depends on how good the person welding the filter back up is. Most cars don't have clear...

    Pretty common issue with gutted DPF's Check the seal between the bonnet and bulkhead, and tailgate in case they are worn. Most people just select recirculate when stationary.

    The one on mine was the same, one block. Mine is mapped and produces next to no smoke, the only difference is it smells a bit more. It will be ok for a few days (mine was) just get it mapped out sooner rather than later.

    Should be ok, if you have access to VCDS reset the DPF ash mass value to zero to keep any regeneration at bay until you have it mapped out correctly.
