Hi there.
I'm the owner of 2009 Polo Bluemotion 9N2 from new, about 50,000 miles on the clock. It's suffered from a clogged DPF for a couple of years. I replaced the DPF at around 45,000 miles with a brand new OEM equivalent after repeated attempts at clearing the original failed and limp mode was constant. The garage that did the work didn't correctly calibrate the DPF after the work, and limp mode is still present with the new DPF. The garage subsequently went out of business.

After some research, I visited a garage who were specialists, they ran some diagnostics (VCDS), took the car out for around 30 minutes, cleared the warning lights and my turbo came back. This cost 50GBP, which I was happy to pay as my turbo was back…for about an hour, then the warning lights returned and limp mode kicked in again.

I can't afford the time and expense of repeated visits to the garage for diagnostics resets, and so I'm looking to purchase VCDS for myself through official channels.

Perhaps inevitably, I have a few pre-sales questions:

* if I trigger a forced DPF regeneration with VCDS, when the soot level gets to a safe level, will limp mode switch off automatically? If not, is there a process to force disable limp mode when DPF loading is low?
* is there a end-of-support window for VCDS 16? I ask because I've seen some good deals now that 17 is out.

Thank you very much in advance.

I'm a bit skeptical about your "OEM Equivalent" DPF.

It's really hard to say whether VCDS alone can fix what ails your car (and is putting it in limp mode). But it certainly will be helpful in diagnosing whatever that is.

Genuine VCDS systems are not limited to a particular major version number. Every genuine VCDS setup we've sold since 2004 can be used with version 17.

Thanks, Uwe. You're not the only one sceptical about the DPF, frankly. I was assured it was equivalent, and the garage that fitted confirmed it was physically the same as the unit that came out, but *shrug*. I'm at the point where I'd be happy if the car just got written off, but I can't afford a replacement right now so I'm following the 'make do and mend' approach.

It's one of these: http://www.autosessive.com/products/13827/catalytic-converter-dpf-combined
