Hi,
Brake lights fine but the error reader got the code:
'Quantity adjuster upper limit reached P1562'
Does this mean anything please?
17970/P1562/005474 - Ross-Tech Wiki

Possible Symptoms

Reduced Power
Engine jerking
Possible Causes
Fuse(s) faulty
Wiring and/or Connector(s) from/to Quantity Adjuster (N146) faulty
Quantity Adjuster (N146) not adjusted
Quantity Adjuster (N146) blocked/faulty
Possible Solutions
Check Fuse(s)
Check Wiring and/or Connector(s) from/to Quantity Adjuster (N146)
Check/Adjust Quantity Adjuster (N146)

Notes
On the 1.9L ALH TDI engine:
The Quantity Adjuster (N146) should ohm test between 0.5 and 2.5 Ω.
With the coolant above 85° C, MVB 001, Field 3 should read between 1.45 to 2.0 Volts.
Not sure what a quantity adjuster is (not really familiar with derv's) but suspect this is a fuelling issue?
Did you have any luck in the diesel section?
