Question 1

What does fault code P173600 mean on a DSG gearbox?

Accepted Answer

P173600 relates to a hydraulic pressure fault inside the DQ380 or DQ381 mechatronic unit — the combined electro-hydraulic brain of your 7-speed wet-clutch DSG gearbox. It tells the car's ECU that hydraulic pressure cannot be maintained correctly, triggering emergency (limp-home) mode.

Question 2

How much does DSG DQ380 mechatronic repair cost near Waltham Cross?

Accepted Answer

MnF Motors prices each repair after a proper paid diagnostic session so you receive an accurate quote rather than a guess. In-house mechatronic repair is substantially less expensive than dealer or exchange-unit pricing. Call 020 8803 1231 for a current price anchor.

Question 3

Can I drive my car in emergency mode to MnF Motors from Waltham Cross?

Accepted Answer

Short distances in limp-home mode are generally possible, but continued driving can deepen hydraulic or clutch damage. We recommend calling us on 020 8803 1231 first so we can advise whether driving or trailering is safer for your specific situation.

Question 4

Is it better to repair or replace a DQ380 mechatronic unit?

Accepted Answer

In the vast majority of P173600 cases the fault is confined to specific internal hydraulic components — solenoids, valve body passages or pressure sensors — that MnF Motors can repair in-house. A full unit replacement costs significantly more and is rarely necessary.

Question 5

Does MnF Motors offer a warranty on mechatronic repairs?

Accepted Answer

Yes. MnF Motors backs its work with a warranty on parts and labour. Full details are available on our Warranty Claims page or by calling 020 8803 1231.
