Received a code p1136 in my 98 Audi A4
Could this hose be the problem?it's sucked flat
Anyone tell what this hose it's called please

That's a vacuum hose. You need to find out where your vacuum issue is.


17544/P1136/004406 - Fuel Trim: Bank 1 (Add): System too Lean

Possible Solutions
Check Mass Air Flow (MAF) Sensor
Check Fuel Pressure Regulator
Check Fuel Pump
Check Intake/Exhaust System for Leaks
Check Secondary Air Injection for Leaks
Check Vacuum Lines for Leaks
Special Notes
Fuel Trim Info
When this fault is stored and external vacuum leaks are not found, less obvious problems may be present:
Check Evaporative Emission (EVAP) Canister Purge Regulator Valve (N80)
Check Brake Booster and Hoses
Check Electric Vacuum Pump ( If Applicable )
Check Crankcase Ventilation System for faulty components. When the PCV or Crankcase Ventilation System is faulty, vacuum is typically present under the oil cap and misfire faults are common.

 

Thanks

 

My Pleasure.
